The inflammatory pseudotumour of the head and neck is a benign lesion, extremely rare outside the cranial orbits. A case is presented of an inflammatory pseudotumour not associated with the IgG4-related disease. The pseudotumour was found as a solitary mass in the infratemporal fossa of a young woman who complained of otalgia and hearing loss. A clear image of the lesion was obtained using an 18F-fluoro-deoxy-glucose (18F-FDG) PET. After the histopathological diagnosis, and treatment with corticosteroids, a second 18F-FDG PET was performed. The metabolic image had returned to normal, and the previously observed mass disappeared. A brief review is presented of the studies examining this type of lesion (AU)
El pseudotumor inflamatorio de cabeza y cuello es una entidad de naturaleza benigna y extremadamente infrecuente fuera de la localización orbitaria. Presentamos un caso de un pseudotumor inflamatorio no asociado a enfermedad relacionada con IgG4, localizado como una masa solitaria en la fosa infratemporal de una mujer joven que consultó por otalgia e hipoacusia. La imagen era evidente en una exploración PET con 18F-FDG. Una vez diagnosticado anatomopatológicamente y finalizado el tratamiento con corticoides, se realizó otra exploración PET con 18F-FDG en la que se normalizó la imagen metabólica y desapareció la masa. Se revisa la literatura sobre este tipo de lesiones (AU)

The PET-FDG is a useful method to assess the post-radiotherapy residual masses in supradiaphragmatic lymphoma patients. We present the case of a patient with residual mediastinic mass revealed by CT after the patient had completed treatment for Hodgkin's disease and in whom the PET study demonstrated a typical pattern of post-radiation pneumonitis. When these patients are re-assessed early after radiotherapy, the different tracer uptake patterns should be taken into account in order to identify the existence of radiotherapy sequela and avoid false positive results.

El PET-FDG es útil en la valoración de masas residuales postradioterapia en pacientes con linfomas supradiafragmáticos. Presentamos el caso de un paciente con masa residual mediastínica en TAC tras completar el tratamiento por enfermedad de Hodgkin y que una exploración PET mostraba un patrón de captación típica de neumonitis postradiación. En la reevaluación temprana de estos pacientes debe tenerse en cuenta los patrones de captación del radiofármaco para identificar la existencia de secuelas de la radioterapia y evitar falsos positivos (AU)
